Description
Technical field
The present invention relates to ophthalmic medical instrument product technical fields, and in particular to protective glass and its application in a kind of art.
Background technique
In ophthalmologic operation, clearly eye fundus image is to influence one of operation most important factor of achievement in operative region.It is existing
For in ophthalmologic operation, wide_angle viewing system is universal in ophthalmologic operation due to it can provide operative region panoramic view the advantages of
It uses.Existing two kinds of wide_angle viewing systems, contact system and untouchable system.Contact system can provide better optics
Resolution ratio and broader area of visual field, but it keeps the stability of eye fundus image very poor vulnerable to the inclined influence of patient's eyeball, from
And influence surgical effect.And untouchable system is not made it by the picture steadiness of eyeball obliquity effects and easily operated property because of it
It is more extensive and generally use.
However, the bitot's patches in surgical procedure cause eyeground visual field difference seriously to be asked using one of untouchable system
Topic.It in the prior art, is currently that cornea is protected by following two mode to prevent bitot's patches from causing damage.It is a kind of
It is cornea to be moistened using balanced salt solution flushing, but since drying is too fast (general 30S~60S), need frequent point in operation
Balanced salt solution causes operating time to increase, while being splashed to the drop on lens surface equally and will affect the eyeground view of patient
It is wild.Another kind is using corneal protection agent, and usually primary amount is 1.5mL, but the use of the shortcomings that corneal protection agent is that can make
It is distorted at eye fundus image, and needs smear once for 20 minutes, operating time also will increase.
Summary of the invention
In view of this, the present invention provides protective glass in a kind of art, be used in Vitrectomy, avoid or reduce equilibrium liquid and
Operating time is saved in the use of corneal protection agent, and image is more clear in art, reduces the difficulty of operation.In order to achieve the above objectives,
The technical scheme of the present invention is realized as follows:
The specific embodiment of the invention provides protective glass in a kind of art, including eyeglass outer surface and eyeglass inner surface；Institute
Eyeglass outer surface and eyeglass inner surface is stated to be made of two arc surfaces；The eyeglass outer surface and eyeglass inner surface are connected structure
At a bowl-shape transparent eyeglass ontology.
Further, center thickness δ < 1mm of the eyeglass ontology.
Further, the diopter of the eyeglass ontology is -5D~5D.
Further, the eyeglass ontology chord length L is 8~15mm.
Further, height H < 7mm of the eyeglass ontology.
Further, the eyeglass ontology is made of the hard material of transparent high oxygen permeability.
Further, the hard material of the transparent high oxygen permeability includes poly- formic acid methyl acrylate (PMMA), acetic acid
Cellulose butyrate (CAB), siloxanes methacrylate (SiMA), fluorine Si acrylate (FSA), fluorine polymer.
The specific embodiment of the invention additionally provides application of the protective glass in Vitrectomy in a kind of art, uses above-mentioned art
Middle protective glass, which comprises
Corneal protection agent is smeared in anterior corneal surface after completion operation preparation；
Protective glass in the art is placed in above the corneal protection agent by the corneal protection agent after the completion of smearing；
After protective glass in the art and the contact surface bubble-free of the corneal protection agent, operation can be carried out.
Further, which comprises
The corneal protection agent includes hyaluronic acid.
Further, the method also includes:
The corneal protection agent usage amount includes 1.5mL.
The present invention has the beneficial effect that:
1) using protective glass and method in art of the present invention, the irregular surface of corneal protection agent can be eliminated, eliminates eyeground
Scalloping phenomenon provides better image quality, to guarantee surgical effect；
2) using protective glass and method in art of the present invention, it can protect cornea, prevent bitot's patches and cause to damage, in art
The eyeground visual field is preferable, to guarantee surgical effect；
3) protective glass and method in art of the present invention are used, need to only smear a corneal protection agent in operation, it is ensured that hand
The continuity of art substantially reduces operating time, improves without intermittent point balanced salt solution or repeatedly smearing corneal protection agent
Patient comfort.
